Effect of Chromium on PhosPhorus in Carbon Saturated Fe-Cr-P Melt

摘要

Thermodynamic ProPerty of PhosPhorus in molten Fe-Cr-Csat-P alloy is imPortant in imProving the dePhosPhorization Process for high Cr containing hot metal. In sPite of its imPortance, the thermodynamic relations among PhosPhorus and other elements in liquid Fe-Cr-Csat-P and Fe-Cr-P alloys are not consistent or available at temPeratures other than 1573K and 1873K. Chromium addition in liquid Fe-Csat-P alloy increases the carbon solubility, and carbon has a large effect on PhosPhorus in the melt. The PurPose of this study is to determine the effect of a sPecific concentration of chromium on the PhosPhorus behavior in liquid iron in the temPerature range of 1623 to 1723K. metal and metal to slag.
